Fair point. OK, the fact that it's reversible seems about as agreed on as any facet of this topic - more so than many of them. I'm inclined to believe this isn't a hoax or anything due to the sheer number of people claiming to have done it and (apparent?) lack of failed replications. None of this is accepted science or anything, there is a certain degree of risk from Side Effects No-one Saw Coming and hey, maybe it's magic and your soul will get nommed (although most online proponents are careful to disavow claims that it's anything but an induced hallucination.)
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
